ISTQB CTAL-TTA : Certified Tester Advanced Level Technical Test Analyst

Within the world of consumer electronics, the amount of embedded software is growing rapidly. The amount of software in high-end television sets has increased by a factor of about eight over the last six years. In addition, the market of consumer electronics has been faced with a 5 -10% price erosion per year. The price of a product is, among a number of other things, determined by the microcontroller used. Therefore, the use of ROM and RAM remains under high pressure in consumer electronic products, leading to severe restrictions on code size.
Within a new high-end TV project, it has been decided to apply dynamic analysis.
Which of the quality goals listed below is MOST appropriate to the project context?

• A. Analyse system failures which cannot easily be reproduced.
• B. Improve system performance by providing information on run-time system behaviour.
• C. Evaluate network behaviour.
• D. Prevent failures from occurring by detecting wild pointers and loss of system memory.

You are working on a complex systems integration project that will soon be deployed to the production environment. This system is replacing a system that was popular with the users and had no outstanding non-functional issues. There are multiple components that interact and these have been developed by various development and testing groups including some outsourced groups. You will be leading the performance testing effort. Although you would prefer to have a dedicated test system for this effort, you will have to use the production system. You can do this testing at a low usage time, but there will be some users on the system and you will be using real data for the tests. You are now planning your performance testing. Unfortunately, there are no requirements for the performance requirements of the system. How do you determine the acceptable performance levels for the various operational profiles?

• A. You should go back to the business analysts and require them to update the requirements to include the performance expectations
• B. You should use industry standard performance benchmarks
• C. You should ask the users what they expect to see for the performance
• D. You should check the performance of the legacy system and use that as a benchmark for the new system

A component has been analysed during a risk-assessment and rated as highly critical. Which of the following white-box test techniques provides the highest level of coverage and could therefore be used to test this component?

• A. Multiple condition testing
• B. Decision testing
• C. Statement testing
• D. Modified condition/decision testing

The following characteristics were identified during an early product risk-assessment for a software system:
* the software system needs to manage synchronization between various processes
* microcontrollers will be used that will limit product performance
* the hardware that will be used will make use of timeslots
* the number of tasks supported in parallel by the software system is large and are often highly complex.
Based on the information provided, which of the following non-functional test types is MOST appropriate to be performed?

• A. Time-behaviour testing
• B. Maintainability testing
• C. Portability testing
• D. Security testing

You are asked to provide a practical and pragmatic testing solution for a commercial system where the main user interface is via the Internet. It is critical that the company's existing good name and market profile are not damaged in any way. Time to market is not a critical issue when appropriate testing solutions are identified to mitigate business risks.
A product risk assessment has revealed the following product risk:
* Abnormal application termination due to connection failure of the main interface.
Which of the following is the appropriate test type to address this risk?

• A. Reliability testing
• B. Operability testing
• C. Performance efficiency testing
• D. Portability testing
